Yumeko has black shoulder length hair and green eyes. Since there is always winter on her home planet Koristar, she mostly only has warm winter clothes. She is a bit short for her age. She has very pale skin. Like all members of AKB0048 she has heart shaped shine in her eyes and hair.
Yumeko is very shy and isn't very confident in her abilities but very caring towards her friends. After being a part of 00 for many years she started to overcome her shyness but is still a quiet person.
Yumeko comes from a planet called Koristar, a planet that has winter for a whole year. She was usually alone and her only friend was Ito Hotaru, who was the reason Yumeko decided to join AKB0048.
Koristar is under entertainment ban so Yumeko never heard music until she was 6. She was playing alone in the forest when she suddenly heard it and went to check what is happening. She met a girl her age who was hiding and listening to AKB songs. When girl noticed her she invited her to join her. It was Ito Hotaru and because of her Yumeko learned about 00. After that she became big fan of AKB, but she never imagined that she could become part of it too, she was satisfied with just being a fan. She spent time with Hotaru every day, but when she was 9, Hotaru told her that her family got chance to move to Atamistar so they are going there. Before they left they promised to each other that they'll meet again one day, when they'll become part of AKB0048 together. Yumeko decided that she'll definitely keep that promise.
Yumeko passed auditions and joined AKB0048 as part of 150th generation. There she was reunited with Hotaru and it was like they never spent time apart. Two of them also became very close with Rei and Tomorin.
